High-strength antiskid glass fiber reinforced plastic stair step

Abstract

The invention discloses a high-strength anti-skid glass fiber reinforced plastic stair step. The high-strength anti-skid glass fiber reinforced plastic stair step comprises a stair step body, a horizontal pedal is arranged on the stair step body, an anti-skid convex face and an anti-skid concave face are arranged above the horizontal pedal, a telescopic groove is formed in the joint of the anti-skid convex face and the anti-skid concave face, a connecting plate A is arranged below one end of the horizontal pedal, a connecting plate B is arranged below the other end of the horizontal pedal, andthe horizontal pedal, the anti-skidding convex surface, the concave surface, the connecting plate A, the connecting plate B and the plane are of an integrated structure. Higher glass fiber content isachieved on a bearing strip, the stair step has more superiority when being used as a step, the step is connected end to end through bolts to form a continuous stair, and the upper surface of the step has a good anti-skid function through a skirting board. The production process of the step is simple and efficient, the step is suitable for large-scale production, and the produced step has the advantages of light weight, high strength, excellent chemical resistance, excellent environmental corrosion resistance, excellent aging resistance and the like.

Description

technical field [0001] The invention relates to the technical field of FRP stair treads, in particular to a high-strength anti-skid FRP stair tread. Background technique [0002] Stairs are a necessary passage between the upper and lower floors, between the left and right floors, or between buildings in daily buildings. The structural staircase is an important component of the industrial delivery room. Its safety is directly related to the personal safety and work safety of the workers. How to prevent the stairs from slipping is more important. The anti-skid of the steps is mainly realized in the following two ways: one is to process the pedals to increase friction by making the pedals raised or patterned to prevent slipping, and the other is to increase friction to prevent slipping by installing anti-slip strips on the ladder. [0003] At present, metal steps are more common, mainly including: steel plates with raised round holes, patterned steel steps, and aluminum alloy ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an advantage of light weight and high strength, which focuses on solving the problems of chemical resistance and corrosion resistance, and is easy to install without long-term replacement; compared with molded FRP grating steps, the production process of this product is simple , high efficiency, suitable for large-scale mass production, and the carrier bar has higher glass fiber, the higher the glass fiber content, the higher the step strength, the high-strength anti-skid FRP stair step, in order to solve the problems raised in the above background technology
